Question Question: BTU Calculation

[toddbatchelder]

Guys, I am having trouble calculating the BTU for a hypothetical liquid cooled radiator loop. Specifically, I need to know the BTU for 4 Corsair XR7 480mm radiators that are daisy-chained together, with 2 of them being used for exhausting heat. Moreover, those radiators would be equipped with 8 Noctua NF-F12 Industrial PPC 3000 PWM Fans, each. The air intake pair of radiators has a dedicated water cooling pump (an Aqua Computer D5 Pump (not the D5 NEXT, I want to save power)) and reservoir (Aqualis 880ml), filed with 780ml of water and has an Aqua Computer Leakshield affixed to said reservoir. The heat exhaust of radiators also has the same setup with the pump, reservoir, and reservoir attachment and both pairs are daisy-chained together in a loop. Lastly, lets say that I have this attached to the liquid cooling block of an RTX 5090 (any from EKWB will do)..., how many BTU's worth of cooling could I expect to get out of it and how cool would it get when overclocking (assuming I can't go above 600 Watts)? Keep in mind that their is only one path for the water to go into the GPU's water block and one path out of there.

Please show step-by-step formulas and how to expand upon said formulas, if I were to scale up the amounts of radiators, fans, pumps, and so-on, in direct proportion (example: scaling-up the whole set up by a factor of 2, save for the supposed water block and the graphics card themselves).

Thanks, guys.
